What is smallest gecko?

The smallest gecko in the world is the Jaragua Sphaero (Sphaerodactylus ariasae), which is found only in the Dominican Republic. It measures only 16.9 mm in length and weighs less than a gram. It is so small that it can comfortably perch on the tip of a match or pencil eraser. Despite its size, it is an active, agile, and ferocious predator for its prey of small insects. The Jaragua Sphaero gecko is at risk due to habitat loss and the introduction of predators such as rats, cats, and mongoose on the islands where it is found.
